High Pass Filter (HPF) and Low Pass Filter (LPF) Mega Thread

[Zbysek]

The single band parametric was needed to switch between fretted and fretless - i found the three band to be overkill for my needs.

1 band parametric

Which one do you use? The only one which I am aware of is EWS BMC...

EWS BMC is what I use. There is also the JHS haunting mids ...

Interesting, thanks for the reply.

Looking at the JHS manual, I would prefer BMC. Minimum frequency range at 400Hz is too high for me...as I often need to work with frequencies around 200 Hz...

Nice thread!
What about Rickenbackers and Hofners and such? Would you use HPF on those or is it more B string oriented?
From analyzing Rick and Hofner frequencies when recording I noticed these guitars have somewhat of a natural HPF.

I used a Hofner as my main bass for a few years, and it was capable of generating a ton of low end, which could too much of a good thing. So a HPF would be very useful for preventing excessive boominess and tightening up the low end.

Same problem with an upright. Couldn’t live without my HPF now.

I really notice it with my 5 string bass. I set it around 40-42 Hz and it is pure magic. I think it should be a must in every pedalboard.

Or amp!

I recently added a Broughton always on HPF to my set up and it's the best thing in my signal chain that nobody will ever notice!

Perhaps

Some of the better, modern amps have adjustable HPF's built in...with others, a pedal or an external device is available. After trying the "Always On Broughton" with my current set up, I would never leave home without it.

I would love to have it tried with with my old Peavey Combo 300 with extra 15" Cab and my old Gibson EB2-DC before I sold them. They were the perfect example of muddy boom!

I've seen those on Reverb. They sure look like an HPF-Pre clone. The frequency range for the HPF is the same.

Looks a lot like fdeck's HPF 3 (which I have and like). I believe he did make the plans publicly available / open source.

Rafferty appears to be based in Ireland. Of so, then it makes total sense that they would copy Fdeck's HPF-Pre: it's open source, and I don't believe Francis ships to Europe.

Last time I checked it was the V2, not the V3.

Open source is not the same as free to commercialize.

Having the toggle switches on the side seems like a weird design choice.

I'm not actually familiar with the laws around that, is there legal prohibitions from doing so? Or was that meant as more of a moral point?

Both.
